 * listener and override the methods for the events of interest. (If
 * you implement the <tt>GraphicsNodeKeyListener</tt> interface, you
 * have to define all of the methods in it. This abstract class
 * defines null methods for them all, so you can only have to define
 * methods for events you care about.)
